Serial No. 495,627.

T o all 'whom it may concern:

Be it known that I, JOSEPH T. FRANTA, a citizen of the United States, residing at Canton, county of Stark, and State of Ohio, have invented a new and useful Sink-Plate, of which the following is a specification.

My invention has relation to sink Vplates adapted for use in sinks, basins'and similar devices.

The object of the present invention is to provide a sink plate which will permit the easy and convenient cleaning or flushing oit' the pipe or sewer to which the sink or basin is connected.

By means of the present invention a hose may be readily attached to the device and water under pressure turned into said pipe or sewer, provision being made for preventing the return of water into the sink during the process of cleaning or flushing. Heretofore it has been necessary when a drain pipe became choked to remove the sink plate and Vthe end of the same.

insert a hose or pipe leading from the spigot or faucet into the drain pipe and to wrap the hose with suitable material so as to fill the sewer opening to prevent the water from backing up and into the sink.

I attain these objects by the construction illustrated in the accompanying drawing, in which- Figure 1 is a plan view of the device illustrating the shut-off )late in a partially closed position. Fig. 2 il ustrates in vertical section my device applied to a sink and showing a portion of the drain pipe connected thereto. Fig. 3 is a perspective view of the threaded plug. Fig. 4 is a vertical sectional view showing a portion of the shut-0H plate and sink plate proper and illustrating the hose connection properly connected thereto.

Similar numerals of reference indicate corresponding parts throughout the several views.

In the accompanying drawing, 1 represents the bottom of an ordinary sink, and 2, To the bottom 1 is connected the sink plate 3 in any convenient and well known manner. The usual form of connection is by means of the flat headed bolts 4, as illustrated in Figs. 1 and 2. Upon the plate 8, and in close contact therewith is pivotally mounted the concentric cut-oit plate 5, said plate being provided with the apertures 6 and 7 which normally lie directly above the apertures 8 and 9 in the sink plate 3.

For the purpose of limiting the movement of the cut-off plate 5 when turned upon its center to cut off the back-flow of water from the drainage pipe, I have provided the button headed screws 10, which are adapted to pass through the slots 11 in the plate 5 and are screwed into the plate 3. Another purpose of the screws 10 is to make provision for holding the plate 5 in close contact with the plate 3', thereby preventing the water, which may back up during the process of clearing the drain pipe, from entering the basin. The annular bead 12 in the plate 3 is for the purpose of holding putty, 13, or like material beneath the plate 3 in order to prevent the passage of water between the plate 3 and the basin 1. At the same time the bead 12 protects the edge of the plate 5 from injury. of providing a pivotal connection for the plate 5, and for the purpose of preventing the water from pushing the plate 5 upward or out of contact with the plate 3 when said plate 5 is placed under the pressure of water which may back up in the drain pipo, the thimble 15 is provided, which thimble passes through the plates 8 and 5 and to which is connected the screw threaded ring 16 as best illustrated in Fig. 2. r1`he ring 16 is adapted to be screwed down upon the plate 5, thereby keeping the plate 5 in close contact with the plate 3. The thimble 15 is provided with the internally screw threaded aperture 17, said aperture being adapted to receive the plug 18, which plug is provided with the vertically disposed plate 19 passing through the aperture 20 in said plug. The plate 19 is provided with the extended flanges 21, which limit the movement of the plug into the aperture 17 and prevent the plug 18 from being screwed entirely through the aperture 17 and accidentally dropped into the sewer.

It will be understood that the screw threads in the aperture 17 are liable to be damaged if not properly protected and it is for this purpose that the plug 18 is provided when the hose connection 22 is not being used. In Fig. 4 I have illustrated the hose connection 22 screwed into the thimble 15 and ready for use. At the lower end of the hose connection 22, the aperture 28 is slightly contracted to give enough stock or material in the casting to permit the screw threaded portion 24 to be formed thereon. At the upper end of the screw threaded portion 24 For the purpose is provided an annular collar 25,

collar is adapted to hold the gasket 26 between the under side of the collar 25 and the top surface of the thimble 15 and ring c 16, thereby insuring a water tight joint between the thimble 15 and the hose connecf` with the apertures 8 and 9 in the plate SI and the plug 18 should be located in the thimble 15. hen it is desired to clean out vthe drain or sewer it will be necessary only to remove the plug 18, insert the hose connection 22 in the aperture 17 and turn the plate 5 upon its center into a position to close the apertures 8 and 9 in the plate 3. A hose may then be slipped over the hose connection 22, the other end being attached to the spigot, when by turning ,on the water at the said spigot the water under pressure will force an opening through the clogged or choked drain pipe and the said pipe may thus be easily and conveniently flushed.

Having fully described my invention what 'I claim as new and desire to secure by Letters Patent, is-

1. In a sink plate, the combination of a fixed plate and a movable plate, said plates provided with apertures, the movable plate provided with slots and the fixed plate provided with screws adapted to pass through the slots, a thimble carried by the fixed plate, a ring connected to the thimble and adapted to hold the movable plate in close contact with the fixed plate, a plug adapted to be secured' to the thimble, all arranged sub` stantially as and for the purpose specified.

2. InV a sink plate, the combination of a fixed and a movable plate, the movable plate located above the fixed plate, said movable and fixed plates provided with a common opening or passage, a thlmble connected to the fixed plate, said thimble provided witha screw threaded inner periphery, means for limiting the movement of the movable plate, a plug adapted to be secured to the thimble, a hose connecting tube provided with a collar and a screw threaded portion, a gasket located between the underside of the collar, and the top surface of the thimble, the movable and fixed plates provided with apertures adapted to register, and means for limiting the movement of the movable plate, 4 Y

substantially as and for the purpose specified. V

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
